Unified technology of full oil well and drainage zone rehabilitation

Abstract

The method for oil well rehabilitation by which the gaps inside the microfracture systems are widened by the influence of strong physics fields and the micro-breccia present in the microfractures are loosened or further broken up. The process allows the oil to flow freely towards the trunk of the oil well from the rehabilitated oil producing layers, where the oil was previously trapped in the microfracture systems.

What is claimed is: 
     
       1. A method of high-precision, full rehabilitation of an oil well and reservoir drainage area in the form of a closed cycle of innovative technical solutions, comprising the steps of:
 (a) preparing an initial free space for movement of individual elements of temporary traps, activated by at least one physics field; 
 (b) distinguishing a first trap among other traps by the diagnosis of radial fracture's traces, appearing on the inner surface of drainage zone by its widest gape caused by serving as a pathway for oil egress from an external boundary to the oil well; 
 (c) Exposing the first trap to radiation influence from at least one radiation source in an amount and for duration effective to stimulate loosening of the particles in the first trap and opening fracture walls of the first trap, facilitating the flow of oil; 
 (d) depleting the first trap characterized by a decrease in the first trap pressure and closing of the trap walls, said decrease and said closing being the main indicators of available degrees of freedom to move the wings of adjacent traps, formed from microfracture hydrodynamic systems; and 
 (e) repeating the steps (a)-(d) for the other traps of the drainage zone, said other traps being numbered in a clockwise direction. 
 
     
     
       2. The method of  claim 1 , the method further comprising: synchronizing the closing of the trap walls of the first trap, said closing of the trap walls determining a movement trend of the adjacent traps, and the radiation influence of the at least one radiation source on wing movement of a next clockwise trap of the adjacent traps. 
     
     
       3. The method of  claim 1 , the method further comprising: prior to exposing a next clockwise trap of the adjacent traps to the radiation influence from the at least one radiation source, computing parameters of an optimal regime of the radiation influence on near bottom hole zone based on results of a diagnostic of the near bottom hole zone. 
     
     
       4. The method of  claim 1 , the method further comprising: waiting until restoration of an initial reservoir pressure, said restoration serving as an indicator of the maximum bottom hole pressure gauge reading, and transmitting a signal to an extraction operator to achieve the initial reservoir pressure at the bottom hole. 
     
     
       5. The method of  claim 4 , the method further comprising: opening a valve by an amount indicated in a rehabilitation program, following transmitting the signal, beginning optimal oil production from the well. 
     
     
       6. The method of  claim 5 , wherein the amount is calculated individually for each well for a period of operation until full extraction of all remaining reserves. 
     
     
       7. A method of high-precision, full rehabilitation of an oil well and reservoir drainage area in the form of a closed cycle of innovative technical solutions, comprising the steps of:
 (a) preparing an initial free space for movement of individual elements of temporary traps, activated by at least one physics field; 
 (b) distinguishing a first trap among other traps by the diagnosis of radial fracture's traces, appearing on the inner surface of drainage zone by its widest gape caused by serving as a pathway for oil egress from an external boundary to the oil well; 
 (c) Exposing the first trap to radiation influence from at least one radiation source in an amount and for duration effective to stimulate loosening of the particles in the first trap and opening fracture walls of the first trap, facilitating the flow of oil; 
 (d) depleting the first trap characterized by a decrease in the first trap pressure and closing of the trap walls, said decrease and said closing being the main indicators of available degrees of freedom to move the wings of adjacent traps, formed from microfracture hydrodynamic systems; and 
 (e) repeating the steps (a)-(d) for the other traps of the drainage zone, said other traps being numbered in a counterclockwise direction. 
 
     
     
       8. The method of  claim 7 , the method further comprising: synchronizing the closing of the trap walls of the first trap, said closing of the trap walls determining a movement trend of the adjacent traps, and the radiation influence of the at least one radiation source on wing movement of a next counterclockwise trap of the adjacent traps. 
     
     
       9. The method of  claim 7 , the method further comprising: prior to exposing a next counterclockwise trap of the adjacent traps to the radiation influence from the at least one radiation source, computing parameters of an optimal regime of the radiation influence on near bottom hole zone based on results of a diagnostic of the near bottom hole zone. 
     
     
       10. The method of  claim 7 , the method further comprising: waiting until restoration of an initial reservoir pressure, said restoration serving as an indicator of the maximum bottom hole pressure gauge reading, and transmitting a signal to an extraction operator to achieve the initial reservoir pressure at the bottom hole.

       12. The method of  claim 11 , wherein the amount is calculated individually for each well for a period of operation until full extraction of all remaining reserves.
